Avalon GloboCare Corp. (NASDAQ:AVCO), a clinical-stage global developer of cell-based technologies and therapeutics, announced that it has successfully completed Phase I first-in-human clinical study of its leading Chimeric Antigen Receptor (CAR) T-cell therapy candidate, AVA-001.
The group said that nine out of ten patients with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) achieved complete remission (CR) - a rate of 90% - within one month after the initiation of AVA-001 CAR T-cell therapy treatment.
It noted that treatment with AVA-001 was generally well tolerated with minimal toxicities and adverse side effects. No neurotoxicity or greater than Grade-1 cytokine release syndrome was observed in this cohort of patients treated with AVA-001. All patients who achieved CR successfully proceeded to allogeneic bone marrow transplant with curative intent.
AVA-001 is a third-generation CAR T-cell therapy which involves the 4-1BB (or CD28) co-stimulation signaling pathway. Accessary laboratory testing that accompanied this pilot clinical study has demonstrated evidence of enhancement in CAR T cell persistence and protection against CAR T cell exhaustion.
Avalon GloboCare said it will present the results of this AVA-001 Phase 1 clinical trial on July 11,2020 at The Eighth Annual Lu Daopei Hematology Forum, the largest Hematology Conference in Asia, which will be held online according to the organizer due to the coronavirus (COVID-19) pandemic.
David Jin, president and chief executive officer of Avalon GloboCare commented: “We are excited and pleased to achieve these successful outcomes with our AVA-001 CAR T-cell therapy. This paradigm of bridging CAR T-cell therapy to bone marrow transplant creates a new therapeutic horizon with curative potential for patients with relapsed/refractory B-ALL and other hematologic cancers.”
